 The failing test case was removed by kre on 2017.12.01.13.25.29 with
 the following commit message, but the PR was not closed at the time.
 I will close it now.

   Since there has been no objection (or even comment) in response
   to my message on tech-userlevel ...

       Subject: tests/lib/libpthread/t_mutex:mutex6
       Date: Thu, 23 Nov 2017 17:34:54 +0700
       Message-ID: <28385.1511433294@andromeda.noi.kre.to>

   which can be found at:
           http://mail-index.netbsd.org/tech-userlevel/2017/11/23/msg011010.html

   which analysed the mutex6 test case of this test, and concluded
   that it was useless, nonsense, and broken (the whole test is just a
   race - not even really using or testing mutexes), let it be henceforth
   forever gone.
